SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 424,454, dated April 1,1890.

Application filed January 24, 1890; Serial No. 337,912- (No model.)

To ctZZ whom it may concern:

Be it known that I, JAMES S. BIERY, a citizen of the United States,residing at Allentown, in the county of Lehigh and State ofPennsylvania, have invented certain new and useful Improvements inSash-Fasteners; and 1 do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. i

This invention relates to saslrfasteners, and is intended moreparticularly to fasten the two sashes of a window against lateralmovement in the window-frame, as when the wind is high, although it mayalso be used to lock the said sashes when desired.

The invention consists, broadly speaking, of a casing seated in the edgeof the sash, a catch pivoted in said casing on a vertical pivot andhaving a serrated tip adapted to engage the head in the window-frame,and a thumb-screw for throwing said catch into operative position, witha spring for retracting it.

The invention also consists in certain details of construction andarrangement of parts for carrying out this general idea, all as morefully described in this specification and illustrated in theaccompanying drawings, forming a part thereof, and in whieh Figure 1 isan inside View of a window with the upper and lower sash-fastenersapplied thereto. Fig. 2 is a. perspective View of the beads on thewindowsash, showing the trans- Versely grooved or serrated stripsapplied thereto. Fig. 3 is a plan, and Fig. 4 a horizontal section,ofthe catch used on the upper sash. Fig.5 is a plan, and Fig. 6 ahorizontal sectional view, of the catch used on the lower sash; and Fig.7 is a perspective detail of the thumb-screw and slotted plate and nutused in the lowensash catch. Fig. 8 is a perspective view of themodification shown in Fig. 6 without the thumb-screw.

It will be understood that I prefer to use two forms of this improvedfastener, one on the upper and the other 011 the lower sash, althoughthat for the upper sash may be used on both sashes if preferred.Although the drawings illustrate but one fastener on each to the entirewindow. These two forms of fasteners possess certain details common toboth, which will now be described.

Referring by letter to the said drawings, 0

designates a casing, preferably of metal, pro-' vided with a transverserecess R in its center and a hole H through its rear face at its outerend. Mounted on a vertical pivot-pin P within this casing is-a catch K,which is shaped like an arc of a circle and at one end has acircumferentially-projeeting tip T with a serrated face, the serrationsS therein running horizontally, as shown. The casing O is set into amortise or recess in the edge of the sash, and is preferably cut away,as .shown at A, so that that portion of the casing which surrounds thehole H, through which the tip projects, shall stand flush with the outeredge of the sash, whereas the remainder of the casing will be embeddedwithin such sash. The outer end of the casing is provided withvertically-extending perforated ears E, which are sunk within shallowrecesses in the edge of the sash, and screws are passed through theperforations therein and into the sash above and below the casing,whereby the latter is removably retained in position, all as will beobvious to and clearly understood by an experienced sash-builder orcarpenter without more explicit explanation or illustration.

The recess R in the upper sash-fastener is closed at its inner end by ashoulder 4 and the catch K is shaped in the form of a quarter of acircle, its inner end normally abutting against this shoulder and heldthere by a coiled or other shaped spring G. A threaded opening is boredthrough the body of the fastener in a horizontal plane parallel with thewindow-pane when the fastener is in place, and in this opening works thethumbscrew M, whose point when screwed in bears against the rear face ofthe catch K and turns it on its pivot to throw its tip T outwardly,

all as shown in Figs. 3 and 4. The thumbscrew has a flattened head m,which is of such a size that it can be turned without striking the glassand the catch operated thereby.

The lower sash-fastener has its recess R provided with an enlargement oropening 0 at its inner end, in which a nut N plays horizontally and atright angles to the plane of the glass. The catch K in this instance isin the shape of a semicircle and has a horizontal slot in its face atits rear end, as shown. The thumb-screw M in this instance enters thefastener at about right angles to the glass, passes loosely through saidslot, and engages the threaded hole in the nut N. A metallic plate maybe provided at the base of the opening 0, against which the end of thethumbscrew bears, whereby when said thumb-screw is turned the nut N isdrawn inwardly. The inner end of the catch K is thereby forcedinwardlyand the outer end or tip T projected through the hole H in thesame manner as above described. A coiled or other shaped spring G isalso provided in this instance, which presses the catch into its normalposition against the force of the thumb-screw; or a metallic plate ordisk D may be provided, having a slot d extending from its center to itsperiphery and screwed or otherwise fastened to the inner face of thesash, and an annular groove 9 in the body or shank of the thumb-screwengages this slot, whereby when the'thumb-screw is turned the nut N isdrawn up in the same manner with the same result; or both the plate anddisk D may be used, if desired, in order to give the device greaterstrength. A plate W, having lateral serrations or notches w, is appliedto the inner face of the outer bead in each groove within which thesashes slide, and when the catches K are pressed outwardly theserrations S in their tips T engage with the serrations w in saidplates, whereby the sashes are locked against vertical movement, thusrendering the device a sash-lock, although it will be understood thatsaid serrations and plate may be entirely omitted, if preferred, Withoutdefeating the principal aim of the device.

The important end and object of this invention, as will be at onceapparent from the above description of its details and their operation,is to prevent lateral movementof the sashes in the grooves in thewindow-frame. In their normal positions the catches K do not in any wayinterfere with the raising and lowering of the sashes; but when the tipsof said catches are thrown outward by turning the thumb-screws thesashes are pressed inwardly thereby closely against the inner verticalbeads of the groovesin which they slide, and all rattling of the sashesis prevented. At the same time the employment of the serrations in theends of the tips and of the plates upon said beads in no way interfereswith such action of the catches or prevention of lateral movement of thesashes, but simply adds the feature of a vertical locking of the sashesand renders the ordinary sash-lock between the central cross-bars of thesashes unnecessary.

Considerable departure may be made from the construction above describedwithout changing the nature and scope of the inven tion, and I thereforedo not limit myself tothe details set forth. I prefer, however, to

use the lateral thumb-screw and its casing on the upper sash, in orderthat the fastening may pass freely by the upper rail of the lower sash,and the transverse thumb-screw on the lower sash or wherever possible,because it extends straight into the room and can be more easilyoperated by the user. I also prefer to provide the tips with theserrations described and to employ the notched plates in the grooves,because they add but little to the cost of the completed article andconsiderable to its value, as above set forth.

This improved fastener can be put into the sash when the window is newlymade, and as the sash and frame contract by drying and shrinking,andmore lateral play between them is thereby created, it will be useful fortightening and fastening the sash until the latter has the unusual playof half an inch, that being preferably the length of the tip. As is wellknown, the sill of a window-frame slopes outward. The fastener on thelower sash presses it inwardly into the obtuse angle formed by this sillat the lower part of the frame, thus preventing cold air and rain fromblowing in under the lower sash. r

In order to accommodate the fastener to sashes of different thicknesses,a longer or shorter thumb-screw may be used or a catch of a greater orless circle.

Having thus described my improved sashfastener, what I claim as thesalient. points thereof is-= 1. The herein-described sash-fastener, thesame comprising a catch seated in the edge of the window-sash, andmeans, substantially as described, for moving it transversely to theplane of the window and throwing its tip against the bead in the windowframe, as and for the purpose set forth.

2. A sash fastener comprising a casing seated in the edge of thewindowsash, a catch mounted on a pivot therein and having a tip, aspring holding said catch in normal position, and means, substantiallyas described, for turning said catch on its pivot and throwing its tipagainst the bead in the window-frame, as set forth.

3. A sash fastener comprising a casing seated in the edge of thewindow-sash and provided with ahorizontal recess, an arcshaped catchloosely mounted in said recess on a vertical pivot and having a tipprojecting outwardly through the side of the casing, a spring holdingsaid catch in normal position, and means, substantially as described,for turning said catch on its pivot and throwing said tip against thebead in the windowframe, as set forth.

4.. A sash fastener comprising a casing seated in the edge of thewindow-sash and provided with a horizontal recess opening inwardly and ahole opening outwardly, an areshaped catch loosely mounted in saidrecess on a vertical pivot and having a circumferentially-projecting tipadapted to pass through said hole, a spring holding said catch in normal position, and a thumb-screw engaging a threaded opening and turningsaid catch against the force of said spring, as and for the purpose setforth.
